Decarboxy Carnosine HCL, also known as N-acetylcarnosine hydrochloride, is a synthetic derivative of carnosine. Carnosine and decarboxylated carnosine possess excellent antioxidant and anti-glycation properties, leading to their widespread use in anti-aging products.
Carnosine is a dipeptide composed of β-alanine and histidine. Decarboxylated carnosine has one less carboxyl group (-COOH) than carnosine. This structure improves its absorption and permeability to the skin.
